CHARGENG=SHOT FOR SHRAPNEL.

SPECIFICATION forming part of Letters Patent N 0. 727,132, dated May 5,1903.

Application filed December 8,1902. Serial No. 134,422.

(No specimens.)

To all whom, it may concern:

Be it known that I, ALBERT HAASE, a subject of the Emperor of Germany,and a resident of Essen-on-the-Ruhr, Germany, have invented certain newand useful Improvements in Charging-Shot for Shrapnel,of which thefollowing is a specification.

The invention relates to charging-shot for shrapnel, and has for itsobject to so increase the power of penetration of the shot that theycan, in contradistinction to the shot heretofore employed in shrapnel,penetrate steel shields, which are recently coming into use inconnection with field artillery. This :5 object is attained according tothe present invention by having the charging-shot consist of an alloy ofsteel with one or more of such metalsfor example, Wolfram, nickelas willlend to the steel a greater resistance to compression and a greatertoughness, combined with greater specific gravity. If, for example, forthe manufacture of the shot one selects a Wolfram-steel with up to tenper cent. Wolfram, an essential increase of strength and toughness overthe usual carbon-steel is obtained, which specifically increases if thealloy has mixed with it nickel, chromium, and molybdenum. Accordingly asone attaches importance to obtaining a particularly hard or aparticularly heavy shot the composition of the steel alloy will bevaried. For example, by the addition of thirtyseven per cent.wolfrain aremarkable strength is attained with a specific gravity of 9.82.

On the other hand, by the use of an alloy of steel with nickel a verysignificant resistance to compression and toughness are obtained,

while the specific gravity increases but a coinparatively slight amount.In each case, however, by the'use of charging-shot produced 40 from sucha steel alloy a penetrating power will be attained, other conditionsbeing equal,

by the high resistance to compression and toughness of the shot, incombination with large specific gravity, which the protectingshields onfield artillery in use at the present time will be incapable ofwithstanding.

The form of the shot is immaterial to the essence of the invention.

Having thus described the invention, the following is what is claimed asnew therein:

1. Charging-shot forshrapnel, consisting of an alloy of steel with ametal such as Wolfram or the like which lends to the steel a greaterspecific gravity, and under otherwise equal conditions increases itspenetrating power.

2. Charging-shotforshrapnel,consistingof an alloy of steel with a metalsuch as nickel which increases the resistance of the shot tocompression, and increases its toughness and consequently itspenetrating power under otherwise equal conditions.

3. Charging-shotforshrapnel,consistingof an alloy of steel with a metalsuch as Wolfram which increases its specific gravity, and a 6 5 metalsuch as nickel which increases its toughness and resistance tocompression whereby the penetrating power of the shotis increased.

The foregoing specification signed at Dusseldorf this 25th day ofNovember, 1902.

ALBERT HAASE.
